Answer:

Explanation:As previously stated, DNA is a macromolecule that's made up of individual subunits called nucleotides. Each nucleotide has three parts:

Brought to you by Sciencing

A deoxyribose sugar.

A phosphate group.

A nitrogenous base.

DNA nucleotides can contain one of four nitrogenous bases. These bases are adenine (A), thymine (T), guanine (G) and cytosine (C).

These nucleotides come together to form long chains known as DNA strands. Two complementary DNA strands bond to each other in what looks like a ladder before winding into the double helix form.

The two strands are held together through hydrogen bonds that form between the nitrogenous bases. Adenine (A) forms bonds with thymine (T) while cytosine (C) forms bonds with guanine (G); A only ever pairs with T, and C only ever pairs with G.

Complementary Definition (Biology)

In biology, specifically in terms of genetics and DNA, complementary means that the polynucleotide strand paired with the second polynucleotide strand has a nitrogenous base sequence that is the reverse complement, or the pair, of the other strand.

11. Punnett squares can also be used to predict genotypes of the parents. A guinea pig with short hair is crossed

emmainna [20.7K]

Answer:

Ss × ss

Explanation:

This question involves a single gene coding for hair length in guinea pigs. The alleles for short hair (S) is dominant over that of long hair (s).

According to this question, a guinea pig with short hair (S_) is crossed to one that has long hair (ss) to produce offsprings that have 44 short hair and 46 long hair. This number of offsprings produced indicate a ratio of 1:1, which can only be produced if the short haired guinea pig is heterozygous i.e. Ss.

Therefore, the genotype of the parents are Ss (short hair) and ss (long hair) i.e. Ss × ss. This combination will produce offsprings with the following proportion: Ss (1) : ss (1).

Which term best describes the movement of water molecules in and out of a cell

stiv31 [10]

The movement of water molecules in and out of a cell is called osmosis.

Osmosis, or the diffusion of water molecules, is when water molecules flow in or out of a cell from high to low concentrations (down their concentration gradient). The ultimate goal of osmosis is to establish equilibrium between the cell and its outer environment.

What is the physiological response to hypoxia?

Alex17521 [72]

Answer:

In most tissues of the body, the response to hypoxia is vasodilation. By widening the blood vessels, the tissue allows greater perfusion. By contrast, in the lungs, the response to hypoxia is vasoconstriction.

Which nims command and coordination structures are offsite locations where staff from multiple agencies come together? answer ic

ivolga24 [154]

Emergency Operations Centers (EOCs) are the National Incident Management System (NIMS) command and coordination structures that are offsite locations where staff from multiple agencies come together.

Emergency operations center (EOC) is a control facility that functions mainly for incident response. This center serves as a central intelligence arena where response team personnel and decision makers gather and analyze extremely important information, organize response activities, make decisions that guards life and property, communicates with staff and response team personnel and ensure the consistent existence and operation of the organization.
